Back around 1960, at school I enjoyed a laboratory lecture on liquid nitrogen, watching a deep frozen squash ball being shattered at a temperature well below that at which it turns from a rubber into a glass, and then seeing a nail being driven into a block of wood with a hammer whose head was made of frozen mercury.  The repeated impacts left an impression of the nail head in the soft metal.

Recently we were treated to a repeat of a three part series,

My attention was recently drawn to a link to the Science Codex, which begins:

What do you say to Pluto’s demotion to “dwarf planet” status?  I did not approve of the demotion, but a few days ago our BBC Sky at Night team did give a reasonable reason why it does require a new category.  With Neptune, one can say “planets end here”, while Pluto is the first of many bodies such as the remarkable Eris that we now know inhabit the Kuiper Belt. 

Pluto really does seem to have captured people’s imagination.  With the announcement that the (dwarf) planet is larger than we thought, a neighbour was asking me how one measured its size.

This got me looking up some values in Pluto Is Larger Than Thought, Has Ice Cap, NASA Probe Reveals, from space.com.

The new measurement of Pluto is 1,473 miles (2,370 kilometers) across

The previous estimate from Earth was 1,430 miles (2,301 km).
